    <p>Well it's C not python, but this works for me. I named the menu "mymenu" that way you can style it without using GtkLabel which would affect any other labels in the application.</p> <pre><code>/* COMPILE WITH: gcc -Wall -o icon3 `pkg-config --cflags --libs gtk+-3.0` icon3.c */ #include &lt;gtk/gtk.h&gt; #include &lt;string.h&gt; /* for CSS */ static void cb_left_click(GtkStatusIcon *icon, gpointer data) { static GtkWidget *window = NULL; if (window == NULL) { window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_title(GTK_WINDOW(window), "Status Icon"); g_signal_connect( window, "delete-event", G_CALLBACK(gtk_main_quit), NULL ); gtk_widget_show(window); } } static void cb_right_click(GtkStatusIcon *icon, int button, int time, gpointer data) { GtkWidget *menu; menu = gtk_menu_new (); gtk_widget_set_name(GTK_WIDGET(menu),"mymenu"); GtkWidget *item1 = gtk_menu_item_new_with_label("First"); GtkWidget *item2 = gtk_menu_item_new_with_label("Second"); gtk_menu_shell_append(GTK_MENU_SHELL(menu), item1); gtk_menu_shell_append(GTK_MENU_SHELL(menu), item2); gtk_widget_show_all(menu); gtk_menu_popup(GTK_MENU(menu), NULL, NULL, gtk_status_icon_position_menu, icon, button, time); } int main(int argc, char *argv[]) { GtkStatusIcon *icon; /*-- CSS ------------------*/ GtkCssProvider *provider; GdkDisplay *display; GdkScreen *screen; /*---------------------------*/ gtk_init(&amp;argc, &amp;argv); icon = gtk_status_icon_new_from_stock (GTK_STOCK_MEDIA_PLAY); g_signal_connect (G_OBJECT(icon), "activate", G_CALLBACK(cb_left_click), NULL); g_signal_connect (G_OBJECT(icon), "popup-menu", G_CALLBACK(cb_right_click), NULL); /*---------------- CSS ----------------------------------------------------------------------------------------------------*/ provider = gtk_css_provider_new (); display = gdk_display_get_default (); screen = gdk_display_get_default_screen (display); gtk_style_context_add_provider_for_screen (screen, GTK_STYLE_PROVIDER (provider), GTK_STYLE_PROVIDER_PRIORITY_APPLICATION); gsize bytes_written, bytes_read; const gchar* home = "/home/mike/icon3.css"; GError *error = 0; gtk_css_provider_load_from_path (provider, g_filename_to_utf8(home, strlen(home), &amp;bytes_read, &amp;bytes_written, &amp;error), NULL); g_object_unref (provider); /*-------------------------------------------------------------------------------------------------------------------------*/ gtk_main(); return 0; } </code></pre> <p>Css file:</p> <pre><code>#mymenu { background-color: white; color: green; font-weight:bold; } #mymenu :hover { background-color: red; color: blue; font-weight:bold; } </code></pre>

    1. COBeing unfamiliar with C, I'm struggling to get this to work. To the best of my translation abilities, this is the same as what I am doing, the difference is that you're using #mymenu instead of the type. Regardless, the background isn't being set. Are you on Ubuntu as well, could you post a screenshot of it in action? When I attempt to compile it as shown in the commented part of the code, I get several [undefined errors](http://i.imgur.com/LfsQB.png). I would prefer Python, since I'm unsure if something being done in the C code above that would count as a missing step in my own code.

    2. COI'm on Ubuntu Natty, gtk+-3.2.3. Sorry I don't know Python at all. In your function css_provider.load_from_data() you have the same background-color for the normal state as you do for the hover and selected states: #f00. http://img809.imageshack.us/img809/1474/iconcd.png

    3. COI finally found it, and it may have had to do with the difference in our Ubuntu or GTK3 versions. I've posted my answer separately. Thanks for your efforts though and at least looking at the question.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
